If you read the accound carefully, Genesis does not say that God "created" the sun, moon, and stars on day four.
Yes it does. It literally says that (well, not the moon, but the stars). You want to copy your version of day four onto the forum?
Where did the light come from on day one, if not from the sun?
That's a good question. Perhaps you should ask the Bible?
"God proceeded to make" the luminaries in that the Sun, moon, and stars could now be seen from the earth.
Before actually making the stars. I guess it's possible for God to make the light coming from the stars before actually making them.
As to plants not mentioned in Genesis, "You are worthy, Jehovah, even our God, to receive the glory and the honor and the power, because you created all things, and because of your will they existed and were created." (Revelation 4:11)
Glad that tid bit was added centuries later.
King James version: (notice how it isn't heavens here? I guess 'heaven' was synonymous with space.)
1: In the beginning God created the heaven and the earth.
2: And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
3: And God said, Let there be light: and there was light.
4: And God saw the light, that it was good: and God divided the light from the darkness.
5: And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
6: And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
7: And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.
8: And God called the firmament Heaven. And the evening and the morning were the second day.
9: And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.
10: And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.
11: And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.
12: And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good.
13: And the evening and the morning were the third day.
14: And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
15: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
16: And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
17: And God set them in the firmament of the heaven to give light upon the earth,
18: And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
19: And the evening and the morning were the fourth day.
Seems like someone has a bad, bad case of Cherry pickin'.
